Angle a,b,c equals 222; because angle a and b already is 180; so there is a right angle in the top with a 48 degree next to it so add then up and its 138; now subtract 180 which is the total of the total angels with 138 and you get 42; now add that to 180 and you get your answer which is 222.

Does anyone know how to solve the equation ln 2 - ln(x - 8) = 4, giving nearly 80 points

RoseWind [281]

Answer:

x= 8.1353

x= 8.135 (rounded to the nearest tenth-thousandths)

x= 8.14 (rounded to the nearest thousandths)

x= 8.1 (rounded to the nearest tenth)

Step-by-step explanation:

Note I am not 100% sure with my answer

2 − ln (x − 8)= 4

−ln (x − 8) + 2= 4

−ln (x − 8) + 2 + −2= 4 + −2

−ln (x − 8)= 2

−ln (x − 8)/−1= 2/−1

ln (x − 8)= −2

ln (x − 8)= −2

e^ln (x − 8)= e^−2

x − 8= e^−2

x − 8= 0.1353

x − 8 + 8= 0.1353 + 8

x= 8.1353

1. In the given figure. BEST is a cyclic quadrilateral. ES is produced so that BE=SN. If ET is the bisector of angle BES, prove

padilas [110]

The triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral.

<h3>How to determine the existence of an isosceles triangle</h3>

In this question we must apply geometric properties of angles and triangles to determine that the triangle NET is an isosceles triangle. Isosceles triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.

Now we proceed to prove the existence of the isosceles triangle:

BE ≅ SN Given
ET is the bisector of ∠BES Given
ET/ES = ET/EB Definition of proportionality
ES = EB (3)
ES ≅ EB Definition of congruence
ET ≅ TN SSS Theorem/Result

Therefore, the triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral. $\blacksquare$
